Got to say the guy that defrosted his York Champion with a hatchet was in the top 10. Including the park when I went to clear the rest of the ice to assess the damage he came back out with the hatchet.
Whacked thru 3-4 passes with one good whack.

i think the pressures are off!

got a call for a fire house in houston. ac not cooling as it should. went out to check. shot infrared on diffusers. sure enough, warm discharge temps. went outside to condenser. threw some gauges on, crazy pressures! you gotta step back and take a look sometimes. I asked chief when last service tech was here, about a week ago. what was the call? he said high temps. (houston is always hot!) okay, what did he do? Said something about a filter, but our filters are clean. see above comment on stepping back and taking a look...on the liquid line, i found three liquid line filters installed obviously in series, with three different install dates on them...need i say more?

1983, condo project had specially designed down flow A/Hs made by York that used off the shelf components. The coil boxes had York badges on them that, when installed, were upside down...no biggie. Buyer complained of no cooling, plaguing my boss for a week. Finally he sent me and my mech out to see what we could do, since the H/O wouldn't listen to any of our techs.

Got there to find he was a retired engineer and that he believed the problem was that the A/H was installed wrong. We left him in the LR, went upstairs and stood there looking at the A/H for a few moments. We looked at each other with that "you thinkin' what I'm thinkin" look, popped the badge out and turned it---and the spec sticker---right side up. After 20 minutes of rattling tools and thumping the cabinet for effect, we came down stairs.

My mech asks, "Notice any difference?". "Yes, you guys are the best...", walks upstairs, sees the swapped tags and says, "...I was right, wasn't I? Those guys (meaning me and Steve as we did the original rough ins and installs) didn't know what they were doing."

...sigh...

Reminds me of a call I got from a movie theater on Christmas day. The ice machine is frozen and one of the kids deiced it with a screwdriver until it started hissing.

Officially, Down for the count

A call, no heat on an oil fired Octpus furnace. Customer; "the pilot will not stay lit" ME" sir this is oil fired it does not have a pilot. Customer: "yes it does, I lite it all the time" Me " could you show me how you are lighting it?" Customer; "Sure......."
He proceeds to tell me how this had to be done quickly.
He lit a match, pushed the reset button, after a few seconds, opened the access door and through the match in....................
I dam near fell on the floor laughing.....

I don't know about the dumbest, but here is definitely the weirdest I've dealt with.
Someone calls in a no cooling. It's about 50F outside, the condenser is frozen solid, so I go to explain the basic limits of the unit to the tenant. Inside the apartment I find an over-sized homemade coffin complete with lid, mattress, and a ventilation system. The guy slept in it (beneath his huge wall painting of Dracula) and the coffins ventilation system just didn't do enough to keep him cool. His solution was to crank up the A/C.

Two15 ton splits,units started and running a few weeks,customer not happy many calls.I get a call on standby.Pressures crazy up and down low and high check condensing unit,see no problem.Go to check TXV's,not there liquid lines ran straight into distributers!

No heat call, go there and right off the bat I notice no power at furnace. Home owner thought the furnace switch is a light switch and turned it off. Sigh had fun explaining why I have to charge for wasting my time.

Oil furnace no heat

I ran this no heat call on a oil furnace that was running a few days before. I asked the lady when the last time they checked the tank and was told that they got oil 2 weeks before. I check the furnace and found water in the oil filter. I went outside and found the garden hose in the fill pipe. I told the homeowner what I found and she yells upstairs for her two boys to get downstairs now. When questioned by Mom they fessed up that they were playing oil delivery guy since they saw the nieghbor get a delivery of oil earlier that day.
